Gh5s Vlog Dynamic Range
These specific tests conclude the maximum useable dynamic range of the gh5 to come in at 11 58 stops using the hgl profile.
Gh5s vlog dynamic range. 400 and 2500 in sdr or 800 and 5000 when shooting in hlg or v log l. Both the sony a7s ii and the fujifilm x t2 have a higher rating. They re just handicapping it as well as forcing strong processing on their prosumer cams to differentiate from their higher end tiers like the eva 1 with real v gamut and v log and an organic looking image. Here s a screenshot of the dynamic range of a few popular cameras.
How many stops are there available exactly. Since you can t shoot raw video on these cameras the next best thing is to ensure you make the best use of the limited bit depth of the 8 or 10 bit footage the camera can capture. Like the gh5 and 4 the gh5s can shoot using panasonic s v log l gamma curve to increase the dynamic range you capture and to make it more usable. Although in shane hurlbut s report he suggests that the dynamic range increases to 11 11 5 rather than 12.
If you are curious about the testing methods used the video does a great job of breaking down the process and how the results were calculated. This is a slightly sub normal rating. The v log for the varicam boasted 14 stops of dynamic range whereas v log for the gh4 gh5 will increase the dynamic base range from 10 to 12. There s nothing compatible about it.
It also looks good beyond that up to 25 600 max iso is 208 000 but the noise reduction is more aggressive. The gh5s produces very clean video at isos as high as 6400. This is how it works. Plan on filming using one of these two isos as they offer the greatest dynamic range.
The camera works by rating the sensor at one of these two isos and then virtually adjusting the iso to your selected iso. In this vid i look into the actual useable dynamic range of the panasonic gh5 also the sony a7iii. The gh5s sensor is capable of delivering up to 14 stops of dynamic range.
